ROAD-SCRAPER.

SPECIFICATION forming part of Letters Patent No.35 2,345, dated November 9, 1886.

Application filed December 7, 1885. Serial No. 184,876. (No model.)

To all whom it may concern:

Be it known that I, JAMES M. ORPUT, of Malta, in the county of De Kalb and State of Illinois, have invented certain new and useful Improvements in Road-Scrapers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in road scrapers and ditch tillers which are mounted on wheels.

One object of the invention is to provide for the location of the scraper practically between the Wheels, and for its extension beyond the wheel-treads, if desired, while allowing the scraper to be set at any desired angle with the line of draft. To this end the spindles of the supporting-wheels are offset or placed out of line with each other, that at the rearmost end of the scraper being in advance of the other.

A second object of the invention is to pro- -vide against the lateral sway or side push of the scraper by reason of its oblique arrangement when at work; and to this end the invention consists in providing a rudder which takes into the ground, and which, as shown,

may be separately actuated and forced into the ground behind the scraper.

A third object of the invention is to better adapt a scraper of this class for filling ditches; and to this end it consists in providing an extension of the axle, whereby one of the wheels may be set to run outside of the ditch, where also provision is made for the attachment of a third horse.

In the accompanying drawings, Figure 1 is a plan View of a wheel-mounted scraper containing my improvements. Fig. 2 is a longitudinal vertical section taken in the line 00 w of Fig. 1, looking in the direction of the arrow applied to said line. Fig. 3 is a plan view of the machine, showing the axle-extension applied thereto for its adaptation to filling ditches.

A is a longitudinal frame-beam, which in Fig. 1 is broken away for a short distance to reveal the lower parts.

B is an axle having wheel-spindles B thereon for the support of the wheels 0, the said spindles being offset or placed out of line with each other, as plainly indicated in Fig. 1. Generally this offset relation of the wheel-spindles will be obtained by making the axle of about the ordinary dimensions and setting the same obliquely to the beam A, as plainly shown in Figs. 1 and 3.

D is a caster-wheel attached to the rear end of the beam A, and E is the tongue proper, which is jointed to the framebeam A by means of side straps, e, and a transverse pin, e, which allows a vertical movement only of the tongue E with reference to the frame-beam A. The joint is in front of the point at which the scraper proper is secured to the machine.

F is the scraper proper, consisting of a board, F, having on its lower edge the forwardly and downwardly inclined metal scraper-plate F. G is acentral longitudinal beam, pivoted at its front end to the frame-beam A by means of an eye, 9, and an eyebolt, g, which latter passes up through the frame-beam A, thus providing especially for a vertical movement and incidentally for a degree of lateral movement on the part of said beam G at its rear end. The lateral movement, however, cuts no material figure in this case.

Near the rear end of the beam G the scraperboard F is attached thereto by a vertical bolt, f, which serves as a pivot on which the said scraper-board may be swung around to vary its angle with the line of draft represented by the frame-beam A. A metal brace, supports the lower edge of the scraper-board F from the rearwardly projecting end of the beam G, as clearly indicated in Fig. 2, said brace 9 being provided with a hole at its front and lower end to admit the lower end of the pivot-bolt f.

G G are side braces of the scraper-frame, which are pivoted at or near their rear ends to the upper edge of the scraperboard F, and which are connected at variable points with the central beam, G, by means of detachable through-bolts g and a series of holes, 9, in the beam G. By means of this construction the' scraper may obviously be set at variable angles with the line of draft of the machine to adapt it for the Various uses of filling or dressing for which the machine may be employed.

As shown in the drawings, and as prefer ably constructed, the braces G G extend a suitable distance back of the scraper-board F,

to allow of the attachment of braces g for the support of the board F by connection therewith in the same manner as described and shown of the brace 9 which is applied to the central beam, G.

G is a cross-bar attached to the rear end of the scraper-beam G, by which the driver, occupying the seat H, may with its feet force the scraper to its work.

I I are levers mounted, constructed, and operating in the usual or any desired manner to raise and lower the scraper.

By means of the oblique construction and arrangement of the axle B, or, more properly, of the offset arrangement of the wheel-spindles B B, the scraper F may be located between the wheels, and may, if desired, extend beyond them, and at the same time may be given any desired inclination for different classes of work to which the machine may be put with out encountering the wheel 0.

J is the rudder.- It is attached to the scraper,

and consists of a metal or metal-shod vertical plate which stands lengthwise with the line of draft-,and is intended to enter the ground to prevent the scraper from being thrown to one side when at work by reason of its inclined direction. Desirably the rudder is vertically adjustable, so that it may be thrown into the ground only when specially required. To this end it is shown pivoted at its front extremity to a plate, j, which is in turn pivotally held by the nut on the bolt f. By the latter pivot the rudder may preserve its proper direction, though the angle of the rudder itself be changed.

J is a post which rises from the rear end of the rudder-plate, and J 2 is a cross-bar secured to the upper end of the post to receive pressure through the feet of the rider. I prefer tolocate the cross-bar J at the rear of and adjacent to the foot-bar G, by which the scraper is depressed, that the driver may conveniently force both downward at the same time or the scraper only.

, J is a suitable form of lateral support for the vertically-movable rudder-plate, consisting of a metal loop, which is attached to the rudder and rises on opposite sides of the beam G and brace 9 L is a detachable extension of the axle,

which as a practical construction may be secured to the machine-frame, as shownthat is, by a horizontal bolt passing through it and the oblique axle B near the spindle of the latter, and-a vertical bolt at the inner end of the extension L, connecting it with the framebeam A. The axle-extension L is of proper length to reach beyond a ditch to be filled, and desirably to giveroom on the remote side of the ditch for a third horse, which, with a pair on the same side with the body of the machine, may be hitched by any suitable form of draft-equalizer, M, substituted in place of the ordinarily-used'double tree N, as will be better seen in Fig. 2. The doubletree or equalizer is preferably attached to the scraper-beam G.

By the use of the caster-wheel D, -in connection with the main wheels 0 O, the frame maintains a permanent position with reference to the ground,and the scraper, being hung between the wheels, will be uniformly'governed by the said upholding-wheels after being set at a particular height by the suspensory devices I. The tongue being vertically flexible a't ein front of the point at which the scraper-beam G is attached, its vertical movement does not affect the action of the scraper, and imposes no objectionable weight or strain on the necks of the horses.

For different classes of work the scraper proper will be set at diflerent inclinations with the line of draft. Thus for merely dressing a road-surface it may be set more nearly at a right angle with said line of draft, while for filling it may be set much more inclined, so that the dirt will in the progress of the machine be carried along toward the rearmost end of the scraper and discharged much as earth slidcs along and is thrown off a plow. To effect this variation of inclination in the scraper requires only that the front ends of the braces G be detached from the beam G and the scraper turned to the angle desired, after which the braces G are again secured to the beam G at the desired points by the holding-bolts g, inserted through appropriate holes, 9, in the beam G for this adjustment.

I claim as my invention 1. In a wheel-mounted scraper, the combination, with an inclined scraper located between the wheels, of the wheel-spindles set out of line in a direction opposite the inclination of the scraper, substantially as described.

2. The combination, with a frame and its supporting-wheels set out of line, as shown, of,

an inclined scraper set between the wheels, and adapted to be adjusted to various angles of inclination with the line of draft, substantially as described.

3. The combination, with a supportingframe, a scraper set obliquely to the line of draft, and a central longitudinal scraperbeam pivotally connected with the frame and supporting the scraper, of a rudder connected with the said scraper-beam and movable independently of the scraper, substantially as described.

4. The combination, with a scraper-frame and two supporting wheels located one at each side of the scraper, of a single transverse axle affording bearings for both of said wheels, and an extension-axle adapted for attachment to the frame in position to extend at one side of the frame, and constructed to afford bearings for one of said wheels, substantially as described.

In testimonythat I claim the foregoing as my invention I affix my signaturein presence of two witnesses.
